EXETER, N.H. (AP) — A New Hampshire sheriff's department says a 29-year-old Exeter mother sold narcotics to undercover agents while her 3-year-old child was in the car.

Officials say Katelyn Kashian was arrested Monday and charged with three counts of sale of a controlled narcotic drug.

Rockingham County Sheriff Michael Downing tells the Portsmouth Herald (http://bit.ly/WuVQeS ) it's likely Kashian will also be charged with endangering the welfare of her child. The child is now in the custody of a family member.

Police say Kashian has been under investigation since September.

She was arrested on Monday after she allegedly gave an officer the narcotic Suboxone in exchange for a substance purported to be heroin.
